SCHOFIELD BARRACKS — A sewer upgrade that will take place along Lyman Road, here, is tentatively starting in late April and lasting through February 2012. Annotated sections on the map above depict traffic control areas that will be affected during the different stages of construction. Traffic control areas either will have lanes open to traffic during construction nonwork hours or may be closed with detours or diverted to a single lane. Motorists are urged to take appropriate steps to limit traffic during these periods and use caution. Inclement weather may cause some delays.
